Liquid projection apparatus |
摘要 |
A method of producing droplets from a nozzle provided on a material layer, the method comprising the steps of supplying liquid to an inner end of an array of nozzles, the nozzles being split into M groups of one or more nozzles, generating one or more firing signals, each firing signal causing sufficient movement of a group of nozzles relative to the liquid such that liquid is projected as droplets from the outer face of the respective nozzles, generating one or more sub-firing signals associated with each group of nozzles, the one or more sub-firing signals causing movement of the group of nozzles which is insufficient to project liquid from the nozzles, the sub-firing signals of adjacent groups having a non-zero phase relationship, wherein the sub-firing signal(s) of at least one group of nozzles is independent of the firing signal(s) associated with that group. |

1. A method of producing droplets from a nozzle provided on a material layer, the method comprising the steps of:
supplying liquid to an inner end of an array of nozzles, the nozzles being split into M groups of one or more nozzles; generating one or more firing signals, each firing signal causing sufficient movement of a group of nozzles relative to the liquid such that liquid is projected as droplets from the outer face of the respective nozzles; and generating one or more sub-firing signals associated with each group of nozzles, the one or more sub-firing signals causing movement of the group of nozzles which is insufficient to project liquid from the nozzles, the sub-firing signals of adjacent groups having a non-zero phase relationship, wherein the sub-firing signal(s) of at least one group of nozzles is independent of the firing signal(s) associated with that group. |
